Full load 36V/8.6A 40V/9.5A 51V/7.6A 63V/9.8A 53V/7.4A 69V/9.6A
* Most ohmmeters do not give accurate readings when measuring less than 1 ohm. The stator can be considered good if a low resistance
reading (continuity) is obtained and there is no evidence of shorted windings (discoloration). Do not confuse a low resistance reading with
a reading indicating a shorted winding.
